Learn Cocoa on the Mac

The Cocoa frameworks are some of the most powerful for creating native OS X apps available today. However, for a first-time Mac developer, just firing up Xcode 4 and starting to browse the documentation can be a daunting and frustrating task. The Objective-C class reference documentation alone would fill thousands of printed pages, not to mention all the other tutorials and guides included with Xcode. Where do you start? Which classes are you going to need to use? How do you use Xcode and the rest of the tools?

Learn Cocoa for the Mac, Second Edition, completely revised for OS X Mountain Lion and XCode 4, answers these questions and more, helping you find your way through the jungle of classes, tools, and new concepts so that you can get started on the next great OS X app today. Jack Nutting and Peter Clark are your guides through this forest; Jack and Peter have lived here for years, and will show you which boulder to push, which vine to chop, and which stream to float across in order to make it through. You will learn not only how to use the components of this rich framework, but also which of them fit together, and why.

Jack Nuttings approach, combining pragmatic problem-solving with a deep respect for the underlying design philosophies contained within Cocoa, stems from years of experience using these frameworks. Peter Clark will show you which parts of your app require you to jump in and code a solution, and which parts are best served by letting Cocoa take you where it wants you to go. The path over what looks like a mountain of components and APIs has never been more thoroughly prepared for your travels. In each chapter, youll build an app that explores one or more areas of the Cocoa landscape. With Jacks and Peter's guidance, the steep learning curve becomes a pleasurable adventure. There is still much work for the uninitiated, but by the time youre done, you will be well on your way to becoming a Cocoa master.
